Neodymium Hydride NdH3 CAS 13864-04-5 For Additives Of NdFeB Permanent Magnet

Neodymium hydride is an indigo blue particle that is stable in dry air but breaks down with water. The compound can be prepared by heating neodymium powder in a quartz tube to 220 ° C and then running a hydrogen stream. Neodymium hydride has specific applications in chemistry and materials science, for example it can be added to neodymium cerium ferroboron sintered magnets to improve their coercivity. This addition method can further improve the performance of magnets by optimizing the microstructure of magnets and improving the grain boundary phase distribution. The preparation process of neodymium hydride is relatively simple, and the powder produced can be evenly wrapped around the main phase, effectively inhibiting the oxidation of the magnet and reducing the oxygen content of the magnet during the sintering process.
